"compact, dual-function/ independent optical switches/ multifunctional metasurfaces without complex hybrid fabrication/ crosstalk... acts as metal along 1 crystal direction/ dielectric along perpendicular direction... incident light polarized along metallic axis triggers localized plasmon resonance for light-concentrating functions/ light polarized along dielectric axis selectively excites light trapping magnetic dipole... ultra-compact optical switches, sensitive chemical sensors, multifunctional metasurfaces"
